Abbeyknockmoy (or Abbey), is a parish, 7 miles south-east of
Tuam, and partly in the barony of Clare, but chiefly in that
of Tyaquin, County Galway.

The name 'Knockmoy'
signifies 'the hill of the plain;' and the abbey which
shares with it in the designation of the parish, was
anciently called 'Monasterium de colle victoriae'.

The establishment is said to have been founded and endowed
in 1180, by
Cathal O'Connor, monarch of Ireland, in
commemoration of a victory obtained by him at its site over Almericus de St. Lawrence. Considerable ruins of the
edifice, which still exist, contain some frescoes, which,
though rude in design, and faded in colour, possess uncommon
interest for the antiquary, as the most authentic memorials
anywhere to be found of ancient Irish costumes.

Abbeyknockmoy is the location
of the ruins of a
Cistercian Abbey of Knockmoy.
Founded by Cathal Crovdearg O Connor, who was buried there
in 1244.
